ABSTRACT
Neuropsychology is a slightly ghoulish discipline, dependent upon nature’s caprice to provide experimental material with which to work. Neuropsychologists seeking to make links between brain and cognition rarely (i.e. only in surgical cases) have control of where and how large a lesion will be made. Most brain injury is a fairly messy affair, usually the result of disease, traumatic injury or cerebrovascular accident. These unpredictable and heterogeneous causes of brain lesions mean that instances of two or more identical lesions will be vanishingly rare. One reason for neuropsychologists’ apparent preoccupation with single cases is simply a paucity of good study materials.
